Choose a primary network interface for the DGX A100 system; for example,
enp226s0.
This should typically be the interface that you will use for subsequent system
configuration or in-band management.
After you select the primary network interface, the system attempts to configure
the interface for DHCP and then asks you to enter the name server addresses.
−
If no DHCP is available, then click OK at the Network autoconfiguration
failed dialog and configure the network manually.
−
If you want to configure a static address, then click Cancel at the dialog after the
DHCP configuration completes to restart the network configuration steps.
−
If you need to select a different network interface, then click Cancel at the
dialog after the DHCP configuration completes to restart the network
configuration steps.
•
Enter name server addresses.

Note: RAID 1 Rebuild May Temporarily Affect System Performance -
When the system is booted after restoring the image and running the
first-boot setup, software RAID begins the process of rebuilding the
RAID 1 array - creating a mirror of (or resynchronizing) the drive con-
taining the software. System performance may be affected during the
RAID 1 rebuild process, which can take an hour to complete.
During this time, the command "nvsm show health" will report a warn-
ing that the RAID volume is resyncing.
You can check the status of the RAID 1 rebuild process using "sudo
nvsm show volumes", and then inspecting the output under /systems/
localhost/storage/volumes/md0/rebuild.
